Hi, I'd like to add to a new keystore value for my elasticsearch on elastic cloud but because I can't get into the elastic machines to send a bin/elasticsearch-keystore command, how do I do this on a 7+ cluster?
Explicitly I'm trying to add a slack hook to my watcher: https://www.elastic.co/guide/en/elastic-stack-overview/current/actions-slack.html#configuring-slack
